Energy Efficiency may be the most discussed words while shopping for electrical appliances. But since the terms are purely technical and there are several variations like capacity, speed and efficiency common man stand puzzled before the shop keeper. So some indications are required to easily identify the power efficiency of an electrical appliance. Here comes a BEE (Bureau of Energy Efficiency) label star rating. The BEE Star Energy Efficiency Labels have been created to standardize the energy efficiency ratings of different electrical appliances and indicate energy consumption under standard test conditions. BEE (Bureau of Energy Efficiency) label indicates the efficiency of the equipment with 1-5 stars. The more star the label bears the more efficient it will be. For example a 5 star rated AC or refrigerator is more energy efficient that an appliance bearing 4 stars. So go for maximum stars while you purchase an electrical appliance. The more stars means more energy efficiency and the more money it will save over the life. Energy saving is for your pocket and for the self reliance of our country.

Building Controls I - An Introduction to Building Controls
Have you ever been in a meeting in a conference room where the room was just too hot? Or too cold? Did you find it uncomfortable and hard to concentrate? Have you ever considered how much money is wasted when things like that are not addressed? What’s the solution? The control system within a building is very important to the energy efficiency of the building, and also to the comfort of the building’s occupants. Visit Energy University at http://schneideru.elementk.com/index.jsp to learn more.
In this class, we will learn a simple definition of a control system, learn the components of a control system, and describe some fundamental types of control and control loops.

The Engineering Toolbox
The Engineering Toolbox is a nice place for Electrical and other engineers for a quick reference into complicated equations and formulae. Visit this site at http://www.engineeringtoolbox.com/ and book mark the same for your future reference. You caqn even sign up for some useful free industry publications from here.
Power Used by a pump – Pump Power Calculation
Pump power is the product of flow rate in cubic metres per second, density of fluid in kg/cubic meter, acceleration due to gravitational force, 9.81 m/second squared and head in metres. The shaft power (kW) will then be this pump power divided by pump efficiency.
PUMP POWER CALCULATION is made easy at http://www.engineeringtoolbox.com/pumps-power-d_505.html

How much energy is your home or office building wasting?
How much energy is your home or office building wasting? Have you ever asked this question yourself? If not try to find out a few loop holes where the energy is losing. The United States Green Building Council estimates that commercial office buildings use 20 per cent more energy on average than necessary. The problem is that we don't know where the energy is lost. A simple solution is remote energy monitoring. Learn more about energy efficiency and save money on regular basis.
Now it is easy to improve your building’s efficiency. Download “Monitoring Energy Use: The power of Information” free of cost from www.sereply.com
